In certain fields, for example, chemistry and physics, it is often useful to convert between various energy units. Common examples are the conversions among frequency (MHz), wavenumber (1/cm), energy (hartrees), molar energy (kJ/mol), and temperature (kelvin).

Energy conversions may be seen as applying the following transformations on the dimensions of the units:

1 second =

c meters

1 kilogram =

c/h per meter

1 kelvin =

k/(h*c) per meter

1 ampere =

1/sqrt(1e7*c*h) per meter

1 candela =

1/(683*c^2*h) per square meter steradian

where c is the absolute value of the speed of light in meters per second, by definition 299792458, h is the absolute value of the Planck constant in joule seconds, approximately 6.6260755&InvisibleTimes;10-34, and k is the absolute value of the Boltzmann constant in joules per kelvin, approximately 1.380658&InvisibleTimes;10-23.

Examples

Convert the wavenumber to frequency, energy, molar energy, and temperature.
